发明名称 METHOD AND APPARATUS FOR PERFORMING A POLISHING PROCESS IN SEMICONDUCTOR FABRICATION
摘要 The present disclosure provides an apparatus for fabricating a semiconductor device. The apparatus includes a polishing head that is operable to perform a polishing process to a wafer. The apparatus includes a retaining ring that is rotatably coupled to the polishing head. The retaining ring is operable to secure the wafer to be polished. The apparatus includes a soft material component located within the retaining ring. The soft material component is softer than silicon. The soft material component is operable to grind a bevel region of the wafer during the polishing process. The apparatus includes a spray nozzle that is rotatably coupled to the polishing head. The spray nozzle is operable to dispense a cleaning solution to the bevel region of the wafer during the polishing process.
